The Problem is.. After I pop in the new card, the boot process hangs at the AGP driver : gagp30kx.sys

No error beeps, just hangs there in any mode, safe or otherwise.

Pull the card, replace with the old 7300 and it fires right up. I'm using it right now to type this.

I'm assuming its an issue w/ the old motherboard & driver recognizing the type/style of card.

Am I just out of luck w/ this and have to take a further step down in video cards? Or is there something I can update?Edit: Learning to read... comments on the product mention an AGP error.. trying to track that down now.

still no luck w/ the 4650. I did replace the power supply w/ a 550 to see if it was drawing too much power from my old 400 PSU. I can load the ATI "AGP hotfix" while in safe mode, but it has a "Device Detection" failure when installing. I'm assuming either the card is bad, or my system simply can't handle it. I'm going to RMA it and try again w/ a slightly less beefy card.

I had this problem and was racking my brain to figure it out:The problem could be your BIOS firmware!I have an ASUS K8V SE Deluxe, and the bios I was using was outdated. Nipped over to ASUS's site, downloaded their bios flash utility and the latest revision and BAM! AGP card worked like a dream.
